Hi,
I dragged home a few boxes of A7/A10 parts tonight and am at a total loss about the engine number. The frame that was included was CA7.32XX, and has all the appearances of an early (1954) swinging arm frame. The light green paint leaves me thinking it was an A7. The Engine, however, is boggling me. The numbers are all genuine (looking) font and I am sure they've not been doctored. The problem is this: the prefix doesn't exist in the books. The engine number is: FA7.XXXXX. It's a really big number that suggests end-of-the-line, but I can't find FA7 anywhere but on frames. The engine is also stamped HHC. What is the collective wisdom? It came with a rev drive on the timing cover, a K2FC mag, and an alloy head that was detached. Thanks for any help!
